Respond to one (1) of the following three
topics with a “primary post” of at least 125 words. Also, please
reply to a fellow student on any topic..

• (1)
  Pacific Lampreys. Watch the video
  on Pacific Lampreys (U.S. Fish & Wildlife Service, 2012). Please
  address the following three questions: (a) where do Pacific lampreys fall
  in the taxonomy of vertebrates? (b) what challenges do Pacific lamprey
  populations face? (c) why are Native American tribes of the Northwest
  concerned about them? (Please note: take care not to confuse the
  Pacific lamprey (described in the video) with the Sea Lamprey, which is a
  completely different species that is considered an invasive species in the
  Great Lakes).

• (2)
  Population Distribution of Termites in a Savanna. Watch the video
  describing Corina Tarnita’s research on the spacing of termite mounds in
  savanna ecosystems (HHMI Biointeractive, 2015). The address the following
  questions: (a) What were Tarnita’s findings about the spacing of termite
  mounds? (b) What does Tarnita think is the main factor that governs the
  spatial distribution of the termite mounds? (c) How do the termite mounds
  benefit other organisms on the savanna?

• (3)
  Supporting the Energy Needs of a Large Brain. Read the article by
  Zimmer (2011). Brain tissue is energetically expensive. For a species to
  evolve a large brain, it may need to make certain adjustments to ensure
  that enough energy is available to support brain function. Zimmer (2011)
  discusses some different adjustments in the human line of descent that may
  have enabled us to evolve larger brain. Explain one of these adjustments.
